    [0001] INSTRUMENT FOR THE OPTIMIZATION OF THE CARVING OF SURGICAL PARTS OF
    [0003] OBJECT OF THE INVENTION
    [0005] The invention, as expressed in the wording of the present specification, refers to an instrument for the optimization of the cutting of surgical pieces of pathological anatomy that provides, to the function for which it is intended, advantages and characteristics, which are described in detail later, which represent an improvement of the current state of the art.
    [0007] More specifically, the object of the invention focuses on an instrument that, formed from a circular blade that acts as an external support for the insertion, first of a staining tool and then of a cutting tool, provides a practical means for Obtain a perfectly carved, dyed and precisely sectioned sample of cylindrical tissue, which represents important advantages compared to the systems currently used for the same purpose, especially reducing the time invested to adapt the dimensions and cutting quality needs of the samples that constitute the surgical pieces of pathological anatomy for their placement in the receptacles of devices that, like the microscope, allow their observation and study.
    [0009] FIELD OF APPLICATION OF THE INVENTION
    [0011] The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of medical / scientific instruments, focusing particularly on the field of surgical tools and utensils for handling and cutting samples of anatomical tissue.
    [0013] BACKGROUND OF THE INVENTION
    [0015] Currently the surgical pieces in pathological anatomy are carved with a common scalpel so the cuts are irregular, time is wasted in adapting the cuts to the "cassettes" that are used as receptacles for their observation and study with devices such as the microscope. Likewise, technicians waste time devastating irregularities of said samples to obtain the one that is finally suitable for the staining and mounting process on the glass. On the other hand, in both operations the surgical pieces are highly fragmented, making it difficult to reorient them if it is necessary to return to them to detail.
    [0017] The objective of the present invention is, therefore, to provide an instrument specifically designed to facilitate said operations, that is, both to obtain the samples, as well as to stain them and that have clean cuts that do not present irregularities that have to be devastated later. .
    [0019] On the other hand, and as a reference to the current state of the art, it should be noted that, at least by the applicant, the existence of any other instrument for carving surgical pieces of pathological anatomy, or of any other invention of similar application, is unknown. , that presents technical, structural and constitutive characteristics equal or similar to those presented by the one claimed herein.
    [0021] EXPLANATION OF THE INVENTION
    [0023] The instrument for the optimization of the carving of surgical pieces of pathological anatomy that the invention proposes allows to satisfactorily achieve the aforementioned objectives, the characterizing details that make it possible being conveniently collected in the final claims that accompany the present description.
    [0025] More specifically, what the invention proposes, as noted above, is an instrument whose purpose is to provide a practical means of obtaining a tissue sample in the form of a perfectly carved, stained and sectioned cylindrical piece with precise cuts and without irregularities that It allows its placement, directly and without the need to cut it again or devastate it, in the cassette or analogous receptacle of the apparatus with which it is to be observed and studied.
    [0027] For this, said instrument is formed, essentially, from a circular external support blade that allows cutting the piece of tissue, and, at least, two insertable tools, first one and then the other, in said support blade, which They consist of a staining tool, with which you regulate the thickness of the piece of tissue to be cut at the same time as it is stained with ink, and a cutting tool with which the piece is sectioned in two parts.
    [0029] Preferably, the external support circular blade is a hollow cylinder that, at one of its ends, which we will call distal because it is the one that is placed in contact with the tissue and opposite to the one used to hold it, has a circular scalpel, preferably incorporated. removably, and at the opposite end, or proximal end, it has a locking groove to receive and lock in different positions, as appropriate, a screw provided in the staining and cutting tools.
    [0031] The objective of this locking system is to regulate the amount of tissue to be extracted, that is, the thickness of the piece by regulating the insertion of the scalpel, and that can vary between one and two centimeters, depending on the degree of insertion in its interior of the staining tool or an additional one in the form of a solid cylinder specially designed for this purpose.
    [0033] In addition to facilitating grip, this external support circular blade has a holding handle at said proximal end.
    [0035] For its part, the staining tool is preferably made up of a hollow cylindrical tube, capable of containing ink inside, whose diameter and length are adjusted to the dimensions of the circular blade to allow its insertion into it.
    [0037] Said tube has, at its distal end, a sponge that protrudes slightly, so that it can be used to stain the tissue with the India ink it contains by pressing on the tissue bounded inside the circular blade described above, and also serve as a stop for The regulate the thickness of the tissue piece to be extracted.
    [0039] This tube also has a screw that emerges perpendicularly on its lateral surface and that serves to effect the aforementioned adjustment of the thickness of the piece of tissue to be extracted, as it is intended to be inserted into the locking groove of the cylindrical blade. .
    [0041] At the other end of the tube of the staining tool, that is to say, the proximal end, it has an external handle to facilitate its handling and a cap to secure the Chinese ink introduced inside.
    [0042] Finally, the cutting tool is preferably formed from a cylindrical body, also with dimensions in accordance with those of the circular blade to be able to be inserted inside it, and which has, at its distal end, a scalpel with a flat blade.
    [0044] Preferably, said scalpel is removable and is attached to the end of the body of the cutting tool through a notch provided for this purpose.
    [0046] In addition, like the staining tool, the body of the cutting tool has a screw that emerges perpendicularly from its lateral surface which, in addition to allowing the regulation of its position within the circular blade, also serves to hold it. and rotating both blades, the circular scalpel and the flat scalpel at the same time, to extract tissue from a surgical specimen.
    [0048] Likewise, this cutting tool also has a handle at the proximal end with the same dimensions as in the staining tool to facilitate grip.
    [0050] It should be noted that, preferably, the dimensions of the described elements that make up the instrument of the invention are provided so that the sample obtained fits into the standardized cassettes that are used as a container for surgical anatomy.
    [0052] With all this, the mode of use of the instrument is, basically, the following:
    [0054] Regardless of the surgical specimen to be carved, the external support circular blade will be used first, with which a homogeneous cylindrical tissue sample is obtained from any surgical specimen.
    [0056] Once introduced into the tissue area to be extracted (example tumor area) without removing said blade, the staining tool is inserted into it to stain the sample.
    [0058] Then, the staining tool is removed and the cutting tool with the rectangular blade is introduced to section into two equal halves, which preferably already have the necessary dimensions for their inclusion in the cassette, and then rotate at the same time. Turn both blades, cylindrical and flat, to detach and extract the tissue.
    [0060] The final result of this procedure with the instrument described is obtaining a cylindrical tissue sample sectioned in half and precisely stained, which allows saving time in grinding, convenience when grinding and standardization of the sample. . This, in turn, allows the Pathological Anatomy technician to reduce the processing time of the samples, since they will not have to devastate as much to obtain a homogeneous sample.

    [0095] As can be seen in Figures 2 to 6, the circular blade (2) with external support is made up of a hollow cylinder (20) which, at its distal end (a) has a circular scalpel (5) and at the proximal end (b), presents a locking groove (21) suitable to receive and lock, in different positions, a locking screw (6) provided both in the staining tool (3) and in the cutting tool (4) for the fixing them when inserted inside the hollow cylinder (20) of the circular blade (2), as shown in figure 9.
    [0097] Furthermore, the circular blade (2) has a handle (22) at said proximal end (b) of the hollow cylinder (20), which, preferably, is made up of T-shaped extensions that extend on opposite sides thereof.
    [0099] Considering Figures 7 and 8, it can be seen how the staining tool (3), preferably, is made up of a hollow cylindrical tube (30), capable of containing ink inside, whose dimensions are in accordance with the dimensions of the circular blade (2) be able to be inserted inside it.
    [0101] Said tube (30) has, at its distal end (a), a sponge (31) that protrudes slightly, to be able to impregnate with the ink that the tissue bounded inside the circular blade (2), also serving as a stop for the regulate the thickness of the tissue piece to be extracted.
    [0103] The tube (30) also has the aforementioned locking screw (6) in the locking groove (21) of the circular blade (2), which emerges perpendicularly at a midpoint of its lateral surface.

    [0109] Like the staining tool (3), in the solid cylindrical body (40) of the cutting tool (4) there is a locking screw (6) that emerges perpendicularly from a midpoint of its lateral surface suitable to fit into the locking slot (21) of the circular blade (2), and at its proximal end (b) also has a handle (42) to facilitate grip.
    [0111] In the preferred embodiment, said hollow cylinder (20) of the circular blade (2) is made of aluminum and is 15 cm long (I), 1.15 cm in external diameter (de) and 1 cm in internal diameter (id).
    [0113] In addition, to incorporate the circular scalpel (5), which is preferably removable, the hollow cylinder (20) has a circular recess (23) 1.5 mm thick in the wall of its distal end (a) with a 4mm depth that allows the insertion of a circular scalpel (5) 0.7 cm in height and 1.07 cm in diameter.
    [0115] Likewise, in the preferred embodiment, the hollow cylinder (20) has a thickening (24) in the vicinity of its distal end (a), which acts as a stop in the incision of the circular scalpel (5) that takes the tissue sample. Preferably said thickening (24) is four millimeters wide and one thick and is located at a distance of 1.6 cm from the cutting end of said circular scalpel (5), so as not to take more than 2 cm of tissue sample, since that if more than 2 cm are inserted the instrument gets stuck in the tissue.
    [0117] For its part, the locking slot (21) extends longitudinally from the proximal end (b) of the hollow cylinder (20) with a length (I) of 3.5 cm and has three locking points, one at 0, 5 cm from said end (b) and another two at 1 cm and 2 cm respectively, allowing to regulate the thickness of the tissue to be extracted from 2 cm or 1 cm of tissue.
    [0119] Likewise, the T-shaped handle (22) is made up of two extensions of 2cm long each.
    [0120] In said preferred embodiment, the tube (30) of the staining tool (3) is also made of aluminum and is 24.5 cm long (I), 0.9 cm external diameter (de) and 0.8 cm wide. internal diameter (di). Furthermore, the handle (32) is defined by a thickening with an open end for the incorporation of the cap (33), which is preferably made of plastic.
    [0122] Finally, following the dimensions of the preferred embodiment of the instrument (1), the solid cylindrical body (40) of the cutting tool (4) is also made of aluminum, has a length (I) of 22.5 cm and a diameter (d) 0.9 cm.
    [0124] Furthermore, as can be seen in Figures 12, 13 and 14, the indentation (41) that serves for the coupling of the flat blade (7) of the distal end (a) of said body (40) has a C configuration, with a central section that extends laterally in two sections, to fit a flat scalpel (7) with a rectangular blade which has a base (70) with extensions (71) to the sides as "legs" that have edges blunt ends which fit over the lateral sections of the indentation (41) of the distal end (a) of said body (40).
